>You've skipped a few steps, until you overthrow the government all you have a broken society with a system of governance that's deemed to be illegitimate, therefore its rules and actions are illegitimate.

Sure, so? We did that quite a few times in the past, that's how we dont' still have Pharaohs.

>If you want to tear up the constitution and implement a new system of governance with "less government" then you're effectively advocating for a revolution. Just be honest and don't try to sell this as an incremental policy change.

Who said it has to be an incremental policy change? The claim I responded to was:

"That's the constitutional bedrock of our societies. That doesn't mean it's always true but if you denounce that as a legitimate and achievable goal then you don't have a society anymore."

You still get one. It's just not something you get while conveniently sitting on your ass and voting once every few years.
